Detailed Description
The invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1, the neutral locked disconnected electric axle assembly of the invention comprises two groups of independent axle assemblies with the same structure, and further comprises a wheel steering locking device arranged between the two groups of independent axle assemblies.
The independent axle assembly comprises a half-axle device, an independent suspension device consisting of a frame connecting piece 21, a bearing frame 22 and a bearing spring 23, and a wheel axial rotation locking mechanism which is arranged between the half-axle device and the independent suspension device and used for locking the wheel 12 to axially rotate.
The half axle device includes an axle 11, a wheel 12 fixedly mounted on one end of the axle 11, a motor plate 13 rotatably mounted on the other end of the axle 11, and a driving motor 14 mounted on the motor plate 13 to drive the axle 11 to rotate.
The wheel steering locking device is used for driving the two wheels 12 to synchronously and reversely rotate in the horizontal plane to form an inverted splayed state after the vehicle stops running and a neutral gear is engaged.
The frame connecting piece 21 is fixedly arranged on the frame 20; the upper end of the bearing frame 22 slides along the vertical direction and is rotatably arranged on the frame connecting piece 21, and the lower end thereof slides and is rotatably arranged on the axle 11; the two ends of the bearing spring 23 are respectively connected with the frame connecting piece 21 and the bearing frame 22.
Preferably, the wheel axial rotation locking mechanism includes a ratchet wheel 31 fixedly mounted on the axle 11, a pawl 32 rotatably mounted on the carrier 22, a pawl spring 33 having both ends connected to the pawl 32 and the carrier 22, respectively, and a pull rope 34 having one end connected to the pawl 32 and the other end wound around the frame connecting member 21.
Referring to fig. 2 and 3, the wheel steering lock device includes a double-rod hydraulic cylinder 45, a link a41, a link B42, a link C43, and a link D44; the double-rod hydraulic cylinder 45 is fixedly connected with the frame 20 by adopting a cylinder frame 24; one end of the connecting rod A41 and one end of the connecting rod B42 are hinged to an output rod A451 in the double-rod hydraulic cylinder 45 at the same point, and the other end of the connecting rod A41 and the other end of the connecting rod B42 are hinged to the two motor plates 13 respectively; one end of the connecting rod C43 and one end of the connecting rod D44 are hinged to an output rod B452 of the double-rod hydraulic cylinder 45 at the same point, and the other end of the connecting rod C43 and the other end of the connecting rod D44 are hinged to the two motor plates 13 respectively.
A sliding sleeve 51 is slidably sleeved on the axle 11, a rolling bearing 53 is sleeved outside the sliding sleeve 51, and the rolling bearing 53 is arranged on the bearing frame 22; the axle 11 is fixedly provided with a driving key 52, and the inner wall of the sliding sleeve 51 is further provided with a key groove matched with the driving key 52 along the axial line.
The working principle of the invention is as follows: assuming that the output rod a451 and the output rod B452 of the double-rod hydraulic cylinder 45 are in the shortest state when the vehicle is in a driving state, two axles 11 in the two half-axle devices are collinear, and planes of two wheels 12 are parallel to each other; when the vehicle needs to be stopped on a slope, the driver controls the double-rod hydraulic cylinder 45 to operate in the forward direction by engaging neutral, so that the output rod a451 and the output rod B452 extend outward. Because link A41 and link C43 are located on each side of axle 11, simultaneous extension of output rod A451 and output rod B452 will cause link A41 and link C43 to push and pull, respectively, the left motor plate 13, thereby causing the left half-axle arrangement to rotate counterclockwise in the horizontal plane, while link B42 and link D44 push and pull, respectively, the right motor plate 13, thereby causing the right half-axle arrangement to rotate clockwise in the horizontal plane; when the double-rod hydraulic cylinder 45 in the wheel steering locking device controls the output rod A451 and the output rod B452 to extend outwards at the same time, the two half-axle devices rotate reversely at the same time, and the two wheels 12 rotate reversely; until the output rods a451, B452 extend outward to the longest position, the two wheels 12 are in the inverted splayed state. When the vehicle needs to continue to run on a slope road, a driver switches the neutral gear to a forward gear or a backward gear, and the neutral gear switching firstly enables the double-rod hydraulic cylinder 45 to work reversely, namely when the output rod A451 and the output rod B452 of the double-rod hydraulic cylinder 45 are shortened inwards, the wheel 12 on the left side rotates clockwise, and the wheel 12 on the right side rotates anticlockwise; when the output rod a451 and the output rod B452 retract to the shortest position, the two wheels 12 return to the original parallel state. The neutral position here controls the forward operation of the double-rod hydraulic cylinder 45, and includes both the neutral position before the vehicle stops on a slope and the neutral position before the vehicle stops on a flat surface.
In the process of synchronous and reverse rotation of the two half axle devices, the bearing frame 22 is driven to rotate around the axis in the vertical direction relative to the frame connecting piece 21, so that the traction rope 34 is wound or released; when the two wheels 12 are changed from the parallel state to the inverted V-shaped state, the frame connecting piece 21 rotates in the positive direction relative to the bearing frame 22, the frame connecting piece 21 gradually releases the traction rope 34, and the pawl 32 rotates downwards around the hinge point under the action of the elastic force of the pawl spring 33 until the pawl abuts against the ratchet wheel 31 on the axle 11; during the process of changing the two wheels 12 from the inverted V-shaped state to the parallel state, the frame connecting piece 21 rotates reversely relative to the bearing frame 22, the frame connecting piece 21 gradually winds the traction rope 34, the pawl 32 stretches the pawl spring 33 under the pulling force of the traction rope 34, and the pawl 32 rotates upwards around the hinge point and gradually moves away from the ratchet wheel 31 until being separated from the ratchet wheel 31.
After the wheels 12 stop running and the neutral gear is engaged, the two half axle devices synchronously and reversely rotate under the action of the output rod A451 and the output rod B452 to drive the two wheels 12 to be switched from a parallel state to an inverted V-shaped structure state, at the moment, if the two wheels 12 roll, the two wheels 12 are enabled to be close to or far away from each other, and the connecting rod A41, the connecting rod B42, the connecting rod C43 and the connecting rod D44 form a transient rigid body structure, so that the two wheels 12 cannot roll along a slope road surface, and the rolling of the two wheels 12 close to or far away from each other is prevented. Thus, the transient rigid body structure not only supports the vehicle The friction between the wheels 12 and the ground is transformed from rolling friction to sliding friction and also causes the two wheels 12 to be subjected to a static sliding friction on the ground in a direction that is oblique to the plane of the wheels, which is a plane perpendicular to the axis of the wheels 12, since the static sliding friction of the wheels 12 is always in a direction opposite to the tendency of the frame 20 to slide down a sloping surface. The outer race of the wheel 12 is normally fitted with a tire, so that the coefficient of sliding friction f of the tire when the wheel 12 slides sideways (sliding with a sliding tendency oblique to the plane of the wheel)1Greater than the coefficient f of static sliding friction of the tyre during its positive sliding (sliding with a tendency to slide parallel to the plane of the wheel)2I.e. f1>f2. Therefore, the maximum static friction force F between the two wheels 12 in the inverted splayed state and the ground1max＝f1N is greater than the maximum static friction force F of the wheel 12 in the parallel state2max＝f2And N is added. N is the supporting force of the vehicle on the slope road surface, and has a magnitude of Gcos θ. If the inclination angle θ of the slope road surface is not set, the downward-sliding component of the vehicle gravity G is Gsin θ, and it is apparent that the downward-sliding component of the vehicle gravity increases as the inclination angle θ of the slope increases. For the satisfaction of F2max<Gsinθ<F1maxEven if the two wheels do not roll, the two wheels 12 in the parallel state can still slide downwards on the slope road surface, but the two wheels 12 in the inverted splayed state of the invention can not slide on the slope. Because the two wheels 12 in the inverted splayed state are locked by the transient rigid body structure, namely the transient rigid body structure effectively prevents the vehicle from moving downwards along a slope road surface, the indirect self-locking of the axle is realized; in addition, the pawl 32 is abutted against the ratchet wheel 31 on the axle 11 under the action of the pawl spring 33, so that the axle 11 is further locked, and the direct self-locking of the axle is realized. After the vehicle stops, when the pawl 32 is not in contact with the ratchet of the ratchet wheel 31, the indirect self-locking of the axle is implemented; when the pawl 32 abuts against the ratchet of the ratchet wheel 31, the indirect self-locking of the axle and the direct self-locking of the axle are simultaneously implemented.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention.
